HIMA HIMax®Digital Output Module X-DO 32 51

Product Description

X-DO 32 51 is a digital NonSIL output module intended for use in the programmable electronic

system (PES) HIMax.

The module can be inserted into any of the base plate slots with the exception of the slots

reserved for system bus modules. For more information, see System Manual (HI 801 001 E).

The module is equipped with 32 digital outputs that can be loaded with a nominal current of up

to 0.5 A per channel. At high level, a voltage equivalent to the supply voltage is present on the

corresponding output.

The outputs are suitable for connecting ohmic, inductive and capacitive loads and lamps.

It can be operated with safety-related modules and other NonSIL modules within one base

plate. Safety-related and NonSIL modules may not be wired redundantly.

The module is interference-free, in particular, with respect to EMC, electrical safety,

communication to the X-SB and X-CPU modules, as well as the user program.

Module and connector boards are mechanically coded, see Chapter 3.6.1. Coding avoids

installation of improper modules.

Refer to the HIMax Safety Manual (HI 801 003 E) for more information on the standards

used to test and certify the modules and the HIMax system.

Safety Function

The module does not perform any safety-related functions.

Each switch of a channel can be individually switched off via the system bus (I/O bus).

The parameters and status for this module must not be used for safety functions.

Reaction in the Event of a Fault

If a channel fault occurs, the affected channel is switched off. If a module fault occurs,

all outputs are switched off.

If the system bus fails, the outputs are de-energized.

The module activates the Error LED on the front plate.

Scope of Delivery

The module must be installed on a suitable connector board to be able to operate. If a Field

Termination Assembly (FTA) is used, a system cable is required to connect the connector board

to the FTA. Connector boards, system cables and FTAs are not included within the scope of

delivery.

The connector boards are described in Chapter 3.6. the system cables are described in

Chapter 3.7. The FTAs are described in own manuals.

Structure

The module is equipped with 32 digital outputs. The outputs are not electrically isolated from

one another and from the voltage supply.

The module is equipped with a current limiting function, which limits the total current of all the

32 outputs. Additionally, the module monitors the total current for overload. If an overload is

present for longer than 100 ms, all the outputs are switched off and switched on again after ten

seconds. If the overload is still present, all the outputs are switched off again for ten seconds.

This process is repeated as long as the overload is present.

If an output overload is detected, the corresponding channel is switched off and automatically

switched on again after five seconds as soon as the overload is no longer present.

The processor system for the I/O module controls and monitors the I/O level. The data and

states of the I/O module are made available to the processor modules via the redundant system

bus. The system bus has a redundant structure for reasons of availability. Redundancy is only

ensured if both system bus modules are inserted in the base plates and configured in SILworX.
